Losing your temper when a serious boundary has been crossed is natural and expected. It had a positive outcome in that it stopped your bad behaviour immediately.

The bystander effect is real, but you should also take this opportunity for self-reflection, because in this case, you were the person behaving badly who instigated the situation.
Serious boundary? He put tits in front of my eyes. Am I supposed to remember to keep my eyes pinned to the floor when out in public? What a terrible way you must live.
I’m afraid to say, that if you want a boundary, go home. Otherwise, accept that you’re in public, and people can and will speak to you.
Also, you’ve just justified being violent in response to someone making sounds with their mouth. I bet you’re a calm person to be around, when everyone does what you want.
You’ve suggested they live in a bubble, yet your comments suggest that you expect no-one to “invade” your blissful little privacy bubble, and believe it’s okay to strike out and be physically violent to others if they do.
> Go out into the world and behave like the GP. Your apparent mental model of society will collapse quickly.
The problem you’ve got is that I will win. If you permit escalating mouth words to physical violence, I’ll have stabbed you in the face for your mouth words before you’ve gotten very far. Subduing your propensity for physical escalation is in your favour.

Yes, unfortunately it seems unlikely you will.
